INSTALLATION INSTRUCTIONS

READ & SAVE THESE INSTRUCTIONS!

Two-Note
Surface-Mounted
Door Chimes

PLANNING

Your NuTone Door Chime is designed for two-door operation.

If the home is multiple-level or large ranch style, two or more
chimes should be used to provide adequate coverage.

Handle the door chime carefully, as you would any precision
instrument.

WIRING

BE SURE HOUSE POWER IS TURNED OFF WHEN WIRING

THE TRANSFORMER. WIRING CONNECTIONS MUST COMPLY
WITH LOCAL OR NATIONAL WIRING CODES.

For a single installation, use NuTone Model 515T or 101T
Transformer.

For two or more chimes, use NuTone Model 105T or 301T
Transformer.

NOTE:

When fastening chime wiring to wall studs and ceiling

joists, care must be taken to avoid possible “shorts” that might be
created by allowing staples or clips to cut through the protective
wiring insulation.

Refer to Figure 1. 

Mount the transformer to a convenient junction

box (attic location is not recommended) or circuit breaker box.
Connect house power leads to transformer leads – black to black
and white to white.

Refer to Figure 2 for single chime installation or to Figure 3

for multiple chime installation

.  Run 2 conductor 18-22 gauge

wire from transformer and the pushbutton(s) to chime location(s).
Bring the wires through the wiring hole in the chime baseplate(s)
and fasten the baseplate(s) to the wall though the mounting holes
with the screws provided. Connect the transformer and the
pushbutton wires to the chime terminal board(s). 

NOTE: Upon completion of installation, if the chime does not

operate properly, check the pushbutton(s) for poor contact or
loose connections. Be certain wires are not touching the tone
bars.

TUBE INSTALLATION (When applicable)

Refer to Figure 4.

Hang tubes onto hanger bracket hooks so that

the longest tube is at the left and the shortest at the right.

MOUNTING COVER

Install the chime cover over the baseplate.

MAINTENANCE INSTRUCTIONS

If chime plungers should ever become “sluggish” in their

movement, clean plungers with a nonflammable cleaning fluid and
wipe dry.

CAUTION: NEVER OIL CHIME PLUNGERS.
